Our Certifications
Steel Sales Co is a steel firm situated in the city of Mumbai. We actively manufacture and supply the Stainless Steel 347 Flanges. We are associated with exporting and distributing the Stainless Steel 347 Flanges too. We are also one of the globally acclaimed stockists of these Stainless Steel 347H Flanges. We are totally fine with assisting our clients by customizing the SS 347 Flanges as per the sizes, shapes, and other dimensions required by them.
These Stainless Steel 347H Flanges formulated by us are composed of elements that are completely meant to provide an excellent collection of mechanical properties to the Stainless Streel 347 grade. The SS 347H grade is an austenitic form of the stainless steel alloys, and these are in their stabilized phase. As for the chemical composition of the SS 347H Flanges, the addition of columbium in the mixture prevents the entire alloy from undergoing the process of carbide precipitation, as a result of which it collaterally fights the intergranular corrosion and provides resistance to the SS 347 against any type of corrosive actions. The resistivity against corrosion that the SS 347 Flanges possess is much higher than that of the SS 321 alloy. The chromium and tantalum stabilization of the SS 347 grade allows these Flanges to combat the creep and stress rupture conditions. These properties of resisting the creep and stress cracking are higher in the SS 347 alloy than in the SS 304 alloy, which is by far the most versatile stainless steel alloy. With the higher carbon concentrations in the SS 347H grade, the heat signatures are maintained very well and the creep properties are improvised too.
The Stainless Steel 347 Flanges engineered by us are supplied to all kinds of industries due to their supreme mechanical properties and their versatility. These SS 347 Flanges operated by us are fabricated into the machines, equipment, valves, pipes, and many other components of industries. These SS 347H Flanges are used for a lot of high-temperature applications like the tubes for heat exchangers, steam pipes with higher pressure, boiler tubes, general piping systems in the refineries, and lastly chemical laboratories for high-temperature experiments.
